332 J. R. MALLOCH. 



27. Agromyza nigrisquama n. sp. 



This species is very similar to the above, but differs in being com- 

 paratively larger, 2*5— 2'75 mm, the wings are more elongated, with the 

 cross veins more consistently approximated, the cheek about one-third 

 the height of the eye, and in its more robust form. 



Type: Tainan, April, 1912. 



Paratypes : Tainan, Takao, and Chip-Chip. Twenty-two specimens. 



OCHTHIPHILINAE. 



Leucopis apicalis n. sj). 



Male: Black, densely covered with silvery pollen. Frons brownish, 

 covered with silvery pollen ; antennae and arista yellow, the latter darkened 

 apically, and the former brownish at base; palpi brown- black; proboscis 

 yellow at apex. Mesonotum in too poor a condition in specimens to say de- 

 finitely if striped, but from the fact that the setulse are arranged in rows 

 I infer that it should have at least distinguishable vittse. Basal segment 

 of abdomen without spots, second and succeeding segments with a narrow 

 median and very small lateral black spots. Legs yellow, coxae brownish, 

 femora, except bases and apices, black, middle of all tibiae brownish, apical 

 tarsal joint on all legs brown. Wings milk-white, veins almost colorless. 



Frons one-third the width of head ; antennae of moderate size, third 

 joint as long as broad, upper apical margin slightly angulate, lower apical 

 margin rounded ; arista not longer than anterior width of frons, basal joints 

 elongated, occupying one-third of the entire length, swollen; cheek barely 

 one third the height of eye. Mesonotum with normal hairing. Hypopygium 

 rather large and knob-like. Legs strong, without bristles. Liner cross vein 

 at beyond the end of first vein and slightly less than one-third from apex 

 of discal cell; last section of fourth vein about 5 times as long as penulti- 

 mate section ; veins 3 and 4 convergent at apices ; last section of fifth vein 

 1^ times as long as outer cross vein. 



Length: 2— 2"5 mm. 



Type: Tainan, February. 



Paratype: Same data. 



Female : Similar to the male in color and structure except that the 

 ovipositor is inconspicuous, and the inner cross vein is situated nearer to 

 the middle of the discal cell. 



Allotype: Same data as type.
